Three small lochs at slightly
different elevations have been swallowed up
by this great sheet of water. The reservoir
is fed by the

pedestals, and at every bend, whether in the
vertical or the horizontal plane, are attached
to massive concrete anchorages. The total
weight of the metal in the six lines exceeds
6,000 tons.
